Abstract (en)
[origin: WO2020098854A1] The invention relates to a clamping system with a stroke-monitored clamping device, in the case of which the clamping system comprises a clamping device and a combination bolt. The clamping device serves for mounting, in the housing, at least one piston which acts on at least three clamping elements, and said clamping device furthermore has a receiving recess for temporarily receiving the combination bolt. The combination bolt is arranged such that it can be fixed in the receiving recess by means of the clamping elements. Here, on the housing, there is arranged an adaptable sensor housing in which an absolute travel measurement system is accommodated. The travel measurement system comprises a sensor IC arranged in a positionally fixed manner in the sensor housing, and comprises a magnetic plate mechanically coupled to the piston. With the present invention, a clamping system composed of a clamping device and of a combination bolt has been developed, the assemblies of which, while taking up a small structural space, ensure a high level of wear resistance, very good operational reliability and a high pull-in force. It is simultaneously the intention for the clamping process of the combination bolt to be monitored.
